Gnnwso vi a citi'zen'of the United States, residingat. Mount Pleasant, in the county of Henry and T clamp for application to railway rails 'to prevent creeping thereof, the object being to provide a simple and inexpensive clamp .01 the class described which, regardless of these characteristics, will be highly efiicient anddurable.

With the foregoing general object in view,

the invention resides in certain novel feations' of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute apart of application and in which: I

Figures 1 and 2 are side elevations of portions of a rail showing the invention applied thereto; Fig. 3 is. an end elevation of the rail and the clamp thereon; Fig. 4 is a vertical transverse section of the rail'and the clamp; Fig. 5 is "a horizontal section on the plane of the line 5-5 of Fig. 3; Fig, 6 is a detail vertical section on the plane the line 66 of Fig. 4:; Fig. 7 is'a perspective view of; one jaw member of the clamp; and Fig. 8 is a similar view of the other jaw member. 1 I

i In specifically describing the structure shown in the drawings above briefly described, similar characters will be placed on corresponding parts throughout the several views and reference will be herein made to the numerous elements by their respective indices. To this end, the numerals 1 and 2 designate the two jaw members of the improved clamp while 3 has reference to the bolt employed for drawing said members into contact with opposite edges of the base of a rail.

The member 1 is stamped from a metal plate 4, the ends of said plate being bent laterally in thesame direction to form a pair of flanges 5 which abut the under side of the rail and serve as means for prevent.-

since the jaw member 2 is held against rotation by the contact of its flange 9 with the end flanges 5 of the member 1.

In use, the devices constructed as above described are clamped at suitable intervals on the rails of a railway in such position as to cause them to abut the ties in case the rails have any creeping action, due to expansion or contraction. It will thus be evident that any movement due to these causes or others will be arrested.

The entire device is simple and inexpensive and may therefore be easily manufactured, pressed steel being used for both members 1 and 2, whereby the manufacturing operation is greatly facilitated. On account of these. advantages, the specific construction shown and described is preferable, but it is tobe understood that within the scope of the invention as claimed I may make numerous minor changes.

I claim:

1. A rail clamp of the class described com prising ajaw member to engage one edge of the base of a rail, said member having a pair of vertically disposed flanges located below its rail engaging portion and having a bolt hole between said flanges, a second jaw member having at one end a hook to engage the other edge of the railbase, the other end of said second jaw member being received slidably but non-rotatably between the aforesaid flanges, and a bolt extending beneath said second jaw member and having one end projecting through the aforesaid bolt hole and provided with a nut, the other end of said bolt havin thereon a hook, the hook of said second ]aw member having a seat receiving said hook of the bolt to prevent rotation of the latter when tightening or loosening the nut.

Q. A rail clamp of the class described comprising a clamping member having means to engage one edge of the base of a rail, said member being provided below its rail engaging means with 'a pair of upstanding flanges and having a bolt hole between said flanges, a second clamping member formed of a single metal plate adapted to underlie the rail base, one end of said plate being bent downwardly to form an upright flange received slidably between the aforesaid flanges and having a bolt hole alined with the aforesaid. hole, the other end of said plate being bent upwardly to form a hook to receive'the edge of the rail base opposite that engaged by the first named member, a clamping bolt extending beneath the aforesaid plate and through the alined bolt holes a nut threaded on one end. of said bolt adjacent said first named clamping member, and a hook on the other end of said bolt, the hook on the aforesaid plate having a seat'receiving the hook of said bolt to prevent rotation of the latter when its nut is being tightened or loosened.

3. A rail clamp of the class described comprising aclamping member having means to engage one edge of the base of a rail, said member being provided below its rail engaging means with a pair of upstanding flanges and having a bolt hole between said flanges, a clamping bolt passing throu h said bolt hole and having on one end a hoo the other end of said bolt being provide with a clamping nut for engagement with the clam )ing meinber, and a second clamping mem er formed of a single metal plate to extend beneath the base of the rail, one end of said plate being bent downwardly to form a flange which is received slidably between the flanges on the first named clamping member, the other end of the plate being bent upwardly to form a hook for engagement with the edge of the rail base opposite that received by the first named clampingmember, the aforesaid flange-having a bolt hole receiving the bolt while the body of the aforesaid plate is formed with a longitudinal slot which opens into said bolt hole at one end and extends along the hook at its other end to partially receive the hook of the clamping bolt to prevent rotation of the latter when the nut thereof is being tightened or loosened.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
